摘要:
An experimental technique for obtaining the spatial size and velocity distributions for liquid or solid aerosols suspended in an air flow is described. The technique leaves the flow undisturbed and allows for a large range of particle sizes and velocities. The successful combination of a Q‐spoiled ruby laser and holography was employed to record the desired information. A helium‐neon laser was used to reconstruct the magnified image which was analyzed using closed circuit television.
